Being a good sport, he actually answered them:What's with all the videos showing people just a few feet from the ground? Can this thing actually go higher or not?Have you ever had an accident?OK, what's it feel like to fly? Links for the rest of our Martin Jetpack coverage: Hands-on ImpressionsFlight Video
